    <p>For my flash app i needed to create a "native extension", which is a native android Java call. This extension builds a string which consist of all image files and their corresponding thumbnails and returns it to Flash. </p> <p>I'm not a Java programmer and this is my first attempt on writing android code. So after 2 days of digging I came up with this:</p> <pre><code>public String getThumbPaths(Uri uri, ThumbContext ctx) { String out = ""; Cursor cursor = MediaStore.Images.Thumbnails.queryMiniThumbnails(ctx .getActivity().getContentResolver(), uri, MediaStore.Images.Thumbnails.MINI_KIND, null); for (cursor.moveToFirst(); !cursor.isAfterLast(); cursor.moveToNext()) { String imageId = cursor.getString(cursor .getColumnIndex(Thumbnails.IMAGE_ID)); String[] filePathColumn = { MediaStore.Images.Media.DATA }; Cursor images = ctx.getActivity().managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, filePathColumn, MediaStore.Images.Media._ID + "=?", new String[] { imageId }, null); String filePath = ""; if (images != null &amp;&amp; images.moveToFirst()) { filePath = images.getString(images.getColumnIndex(filePathColumn[0])); } out += cursor.getString(1) + ";" + filePath+";"; } return out; } </code></pre> <p>and the call</p> <pre><code>ThumbContext ctx = (ThumbContext) context; Uri uri = MediaStore.Images.Thumbnails.getContentUri("external"); // content://media/external/images/thumbnails String paths = getThumbPaths(uri, ctx); </code></pre> <p>Everything works well, except for the speed. I don't know if this happens because of Flash-Java-Flash calls or the piece of code above, which i can't check because the compilation happens inside the Flash. </p> <p><strong>So my question is: can i speed up this code? Maybe do this without second cursor inside the "for" loop?</strong></p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
